rep/stos and rep/mov if the count is not a constant. We could do
  rep/stosl; and $count, 3; rep/stosb
For now, I will lower them to memset / memcpy calls. We will revisit this after
a little bit experiment.

Also need to take care of the trailing bytes even if the count is a constant.
Since the max. number of trailing bytes are 3, we will simply issue loads /
stores.

* Cleaned up and tweaked LEA cost analysis code. Removed some hacks.
* Handle ADD $X, c to MOV32ri $X+c. These patterns cannot be autogen'd and
  they need to be matched before LEA.

* Add patterns to handle GlobalAddress, ConstantPool, etc.
  MOV32ri to materialize these nodes in registers.
  ADD32ri to handle %reg + GA, etc.
  MOV32mi to handle store GA, etc. to memory.

- Use C++ code (rather than tblgen'd selection code) to match the above
  mentioned leaf nodes. Do not mutate and nodes and do not record the
  selection in CodeGenMap. These nodes should be safe to duplicate. This is
  a performance win.
